Do you get any rattles when WOT?

 

Plus the fumes are almost unbearable in traffic [:@]

 

No problems for me...virtually no fumes or leaks that i can find

 

Mine gets some fumes from time to time, mainly with the ac on in traffic. To awnser the ? above is my car is tuned and dead on. Wot awesome but I just notice after the h-pipe it sluggish down low. You win some, you lose some. I made 8 extra rwhp from it, and Im happy for that, hopefully when I get my 4.30's installed next week it will take car of the no bottom end torque
